Can I switch between synthetic and conventional oil?

Yes, it’s possible to switch between them, although it’s best to follow your vehicle’s manufacturer recommendations. If your car is older, consult a mechanic before making a switch.

Is synthetic oil worth the extra cost?

In most cases, yes—especially if you want longer intervals between changes and better protection. For frequent drivers or those in extreme climates, the investment often pays off.

How often should I change synthetic oil?

Many full synthetic oils are rated for up to 10,000 miles between changes, but always check your vehicle’s maintenance guide for specifics.

Power Service: Spring/Summer Maintenance

We all know Power Service is great for treating your diesel engines when the temperature drops. While winter treatment is very important, we can't ignore the fuel the rest of the year. Using additives year-round ensures that you are controlling the lubricity, cetane rating, cold weather performance, improving fuel economy, and overall fuel stability of your diesel engine.

Diesel Kleen + Cetane Boost

When temperatures are above 30°F, add Diesel Kleen + Cetane Boost when you fill up to clean injectors, improve fuel economy, boost power, lubricate pumps and injectors, and restore lost power.

Clear-Diesel Fuel & Tank Cleaner

We recommend using Clear-Diesel at least quarterly (or as needed) to remove existing water in your fuel tank. This product will also disperse contaminants and ensure fuel is stabilized for long-term stroage.

Bio Kleen Diesel Fuel Biocide

If microbial contamination is already present in your fuel (check your filters), you're going to want to treat it with Bio Kleen to kill microbes (bacteria and fungi) first. Once the fuel is treated, add Clear-Diesel to remove the residual water and contaminants.
